My fuel guage on my 2001 saturn L300 is stuck on full.

The gauges are all on a single plug in circuit board that makes up your dashboard.
If the gauge isn't working, it's likely the sending unit attached to the fuel pump, located inside the tank.
Replace the pump, but check all the fuses for the gauge first.

check cluster if bad replace

If it turns over when you turn the ignition key and you have power. Check too see if it is getting gas. The fuel pump could not have enough pressure to start the engine. When you first turn you key on listen and see if you hear the pump runs for a couple of seconds. If no sound probably fuel pump. Do a pressure test first.

Sounds like you have a fuel leak draining the presure in the rail. Check for a bad injector or fuel presure regulator.

Ya, cutting those wires will definately cause the NO START. Depending on what was done, you might be able to fix it, might not. If not, there are ways to bypass the entire system. Here is some good info on the situation, and some possible solutions.

Full bypass works on these car.

Change the spark plugs and wires change the air filter and fuel filter fun some fuel system cleaner through the engine and then change the oil.

NO. Find a shop that knows what they are doing, stay away form chain stores.

Mine was doing same, but also revving up weird. I replaced the Crankshaft position sensor and it didnt work. Today I changed the Engine coolant temp sensor and it fixed my problem. Hope this helps!!

You've got to check the( Fuel-gauge) sender unit which is inside the tank,
it could be faulty or stuck at 'full' position.
Its mostly fitted on top of the fuel tank could be easily accessable form the inside or you may have to drop the tank.

Makes 100% sense to me

I have a 1999 SL1 that I'm having a field day with. I installed a OEM cruise control on the car, took it to the dealer and had them program the PCM to see the cruise.

Cruise works flawlessly, but now I have a Service Engine Soon and Service Lights on all the time (Crank position sensor error and 1 cylinder missfire error) that the dealer cannot get to reset (Car runs perfectly) Dealer has worked on it 4 days so far (at their cost, not mine) they seem to be stumped. I love it!
